Introduction
by ARTHUR C. CLARKE
T he wise science fiction writer prefers to operate in galaxies far, far away and long, long ago, where
he is safe from nagging critics–like the small boy who once told Ray Bradbury he had a satellite moving
in the wrong direction. (“So I hit him.”)
However, by exquisitely bad timing, the setting of this novel occurs practically next door and tomorrow
afternoon. Desperate attempts to persuade publisher Byron Preiss to stop the countdown for a year or so
have been of no avail. By the time these words appear in print, Paul and I may have to eat some of them.
When Phobos was discovered in 1877, it not only made obsolete Tennyson’s “The snowy poles of
moonless Mars,” but it presented astronomers with a phenomenon they had never encountered before.
Most satellites orbit their primaries at substantial distance, in a fairly leisurely manner; our own Moon
takes almost thirty times longer to go around the Earth than the Earth takes to revolve on its own axis.
But here was a world where the “month” was shorter than the “day”! Mars rotates in twenty-four and a
half hours (to the great convenience of future colonists, who need make only minor adjustments to their
watches and circadian rhythms), yet Phobos circles it in only seven and a half!

ARTHUR C. CLARKE'S VENUS PRIME: VOLUME 3
Today, we are accustomed to artificial satellites which perform such feats, thus rising in the west and
setting in the east (see Bradbury, supra ), but the behavior of Phobos was quite a surprise to late-19th-
century astronomers. It was also a bonus to such writers as Edgar Rice Burroughs; who can forget the
hurtling inner moon illuminating the ancient sea beds of Barsoom?
Alas, Phobos doesn’t hurtle very fast, and you’d have to watch for some time to see that it’s moving at
all. And it’s a miserable source of illumination; not only is its apparent size a fraction of our Moon’s, but
it is one of the darkest objects in the Solar System, reflecting about as much light as a lump of coal.
Indeed, it may be largely made of carbon, and altogether bears a close resemblance to the nucleus of
Halley’s Comet, as revealed by a whole flotilla of space probes in 1987. It’s not much use, therefore,
during the cold Martian nights, to warn travelers of approaching thoats, seeking whom they might
devour.
(The erudite Sprague de Camp once pointed out a very peculiar feature of Barsoomian ecology: the
fauna apparently consisted almost entirely of carnivores. The poor beasts must have suffered from acute
malnutrition.)
In “The Wreck of the Asteroid” ( Wonder Stories , 1932), explorers first landed on Phobos and had a lot
of fun bouncing around in its approximately one-thousandth-of-an-Earth gravity. Until one of them
overdid it, achieved escape velocity–and started to fall helpless toward the looming face of Mars . . .
It’s a nice, dramatic situation, which author Lawrence Manning milked for all it was worth. The crew
had to make an emergency take off and race after their careless colleague, hoping to catch up with him
before he made yet another crater on Mars.
I hate to spoil the fun, but that just couldn’t happen. Small though it is (about 20 meters a second,
compared with Earth’s 11,200) not even an Olympic high-jumper could attain the escape velocity of
Phobos–especially when encumbered with a spacesuit. And even if he did, he would be in no danger of
falling onto Mars– because he would still have the whole of Phobos’s eight thousand meters per second
or bital velocity . His trifling muscular contribution would make virtually no difference to that, so he
would continue to move in just the same orbit as Phobos, but displaced by a few kilometers. And after
one revolution, he’d be back where he started.
In The Sands of Mars (1954), I brutally turned Phobos into a minisun (by carefully unspecified
technology) in order to improve the climate of Mars. It now occurs to me that this was a trial run for
blowing up Jupiter in 2010: Odyssey Two .
Soon after the appearance of “Hide and Seek,” another British science fiction writer asked me rather
suspiciously: “Have you ever read C. S. Forester’s short story ‘Brown on Resolution’?”
“No,” I answered, truthfully enough. “I’m afraid I’ve never even read the Hornblower books. What’s it

about?”
Well, it seems Brown was a British seaman in the First World War, armed with only a rifle, who
managed to keep at bay a German cruiser from his various hideouts on a small, rocky island. (A rather
similar story, one war later, was made into an excellent movie starring Peter O’Toole. In Murphy’s War ,
the hero was still coping, more or less single-handed, with Germans.)
I’m sorry to say that I still haven’t gotten around to Forester’s story and missed the chance of discussing
“Brown” with him when we once dined together in the magnificent Painted Hall of the Royal Navy
College at Greenwich. Which was a pity, as it would have given me a chance of trotting out one of my
favorite quotations: “Talent borrows–but Genius steals.”
Decades before the Viking spacecraft gave us our first close-up views of Phobos, it was obvious that a
hunk of rock only a few times larger than Manhattan could possess no trace of atmosphere, still less
harbor any life. Yet unless my memory has betrayed me completely, I seem to recall that Burroughs
once had Mars invaded by marauding Phobians. The economics–not to mention the ecology–of such a
microcivilization boggles the imagination. Once again, I fear, ERB hadn’t done his homework.
(I am still prepared to repeat a statement that I made many years ago: ERB is a much underrated writer.
To have created the best-known character in Western–and perhaps world–fiction is no small
achievement. The Mars novels, however, should be read before the age of sixteen: I hope to revisit
Barsoom in my rapidly approaching second childhood.)
Nevertheless, Phobos once featured rather spectacularly on the SETI (Search for Extra-Terrestrial
Intelligence) agenda. Back in the sixties, the Russian astrophysicist Iosef Shkovskii–best known to the
general public for his collaboration with Carl Sagan on SETI’s sacred book Intelligence in the Universe
(1966)–made an extraordinary suggestion about the little world, based on the long-established
observation that it is slowly falling toward Mars.
I have never decided how seriously Iosef took his theory; he had a considerable sense of humor–which
he needed to survive as a Jewish scientist in Stalin’s time (and a lot later)–but this is how his argument
went:
The slow descent of Phobos is due to the same effect that finally brings down close artificial satellites to
Earth–the braking effect of the atmosphere. A satellite made of dense material will survive a long time;
one with low mass per volume will be brought down more quickly, as was demonstrated by the ECHO
balloon, and later by SKYLAB, which was essentially an empty fuel tank.
Working backward from the drag figures, Iosef calculated that the density of Phobos must be much less
than that of water . This could only mean that it was hollow. . . .
Well, it seemed unlikely that Nature could make a hollow world some tens of kilometers across. Phobos
